Until now, we've internally thought of the CSS "display" property as a single-value property. In practice, "display" is a much more complex property that comes in a number of configurations. The most interesting one is the two-part format that describes the outside and inside behavior of a box. Switching our own internal representation towards this model will allow for much cleaner abstractions around layout and the various formatting contexts. Note that we don't *parse* two-part "display" yet, this is only about changing the internal representation of the property. Spec: https://drafts.csswg.org/css-display
